. Specification forming part of :Letters Patent No. 173,711, datedFebruary' 15, 1876; `application filed December 3,1875.

To all-whom it-may concern:

Be :it `known that I, `DANIEL STRUNK, of Janesville, in the `county ofRock and State Vof Wisconsin, have in venteda new and usefullImprovement in Seeding-Machines; and I d0 hereby declare that thefollowin gis a full and'exact description of the same, `reference`receptacles filling as they revolve and discharging at any suitablepoint of their revolution, the quantity of grain dischargedby the cupsbeing regulated by their capacity by means of an adjustable disk; andits object is j an improved seed dropping mechanism, whereby the desiredqtiantity of grain can be positively sown, the capacity of theseed-receptacles conveniently adjusted without changingthe speed of anyof the parts, and coarse or 'unclean grain sown Without clogging orgrinding.

My invention therein consists principally in dividing the inside of thevertically-revolving cylinder into independent and unconnectedspirally-shaped seed-chambers; further, in the combination of thepeculiar seed-receptacles and the adjustable-disks; and, further,invarious combinations, all as more fully hereinafter explained.

'lo enableothers skilled in the art to make my invention, I now proceedto describe the same in connection with the dra-wings, in which-4 pFigure 1 is a perspective view; Fig. 2, a side elevation, with theseed-cylinder and adjustableA disk removed; Fig. 3, an end elevation ofthe seed-cylinder and adjustable disk; and Fig. 4 is'an end elevation ofthe seed-cylinder.

Like letters denote corresponding parts in each figure.

A represents the outer easing, having an opening, a, on its top, forminga continuation y of the main hopper of the machine, and suitable tlangesaf, by which it is secured in place. B is a cylinder, situated in theeasing A and adapted to revolve therein, being rigidly secured to ashaft, B, which passes entirely through said outer casing, and isrevolved by anysuitable means. On the inside of the cylinder B are castspiral flanges or partitions 10, Which extend at regular intervals theentire ilengthof saidfcylinder, and project inwardly 'froml the shell ofthe same. D is a disk slightly ksmaller than the internal bore of thecylinder IB, andis provided with diagonal slots, adapted to slideoverthe ilanges G,- and pass freely in and `out 'of the cylinder, takingvthe direction of Vtlie langesfbut fitting snugly the `several parts.The disk D is supported upon an arm, E, which is sleeved on the shaftB', and lhas a groove, b, near its end for the reception of a forkedlever, adapted to move said arm and disk. This arm is just large enoughto fill up the central space between the sides of the internal flanges,and thus separates the inside ofthe cylinder into separate andunconnected chambers F, while, by moving the disk back and forth', thesize of these spaces can be regulated at will. VThe cylinder B is closedat one end by a head, G, through which openings G are made, the same innumber as the chambers F. H is a rectangular projection on the inside ofthe outer casing, having a hat, smooth face. rlhe face of thisprojection is about the same in extent as the distance between two ofthe flanges C, one end of the cylinder and llanges bearing against suchsurface in their revolution. I is an opening made in the outer casing atany suitable point, and connects with a part of the open end of thecylinder and with the seed-chambers.

The operation of my device is as follows: The shaft and cylinder beingrevolved, by any of the well-known devices, in the direction of thearrows, the grain in the opening a, by its 'own gravity and by theweight of the superincumbent grain, ows freely and .naturally into theseed-chambers, and is delivered by them into the opening l in regularquantities. The diskis adjusted to make the seed-chambers of the desiredcapacity.

In planting all kinds of grain, and especially unclean grain, chad,dirt, and fine seeds are liable to get past the disk, between it and theheadof the cylinder, and prevent the disk from being moved to itsgreatest limit.

To remedy this defect, l provide the head with openings, beforedescribed, through which the chaff, dirt, and iine' seeds pass, by therevolution of the cylinder and by the incline of the spiral flanges. Thespirally-forined seed-chambers and flanges, besides throwing the dirtthrough the openings, allow the seed to ll them more perfectly anddeliver the saine more easily than if the said flanges Were at rightangles to the head of the cylinder. Y

The seed-chambers, by being independent andunconnected, have theadvantage of delivering positively the same amount of grain in each. Thesurface H, by being about the same size as one of the spaces, preventsthe backward flow orl leakage of the grain, as each succeeding partitioncomes near enough to such surface to stop the ow of the grain through tothe exit after the preceding par-l -tition has passed by the surface andthc grain Letters Patent, is-

1. In a seeding-machine, a vertically-revolving cylinder, havinginternal spiral flanges, forming independent and unconnected spiral]yshaped seed-receptacles, substantially as and for the Ypurposes setforth.

2. The combination withvthe vertically-revolving cylinder, havingindependent and unconnected spirally-shaped seed-receptacles, of

v theadjustable disk, substantially as described and shown.

l3.' The combination, with the cylinder By, of the internal spiralflanges, thev` disk, and the openingsv G( in the head of the cylinder,substantially as described and shown.

4. The combination, with the casing A and cylinder B, ofthe spiralflanges C and surface H, substantially as described and shown.

5. In combination, the casing A, having openings a, and I and surface H,the cylinder B, having internal flanges C and openings Gr', and theadjustable disk D, all substantially as described and shown.

This specification signed and witnessed this 22d day of November, 1875.i DANIEL STRUNK.
